7 Claims,

This invention relates generally to a photocopy or like machine, and more specifically to a photocopy or like machin.,- which is particularly adapted for use in oilices and like places of business which are either not equipped to do, or where it is not desired to do, the development of exposed photo-sensitive paper or like material.

In recent years it has become common in insurance oices, law offices and like places to have photocopies made of various instruments or documents such as Wills, deeds, insurance policies and the like. However, heretofore, unless an oiiice or like place has beenv large enough to maintain its own photocopyr department, it has been customary to send original documents, which were .to be reproduced, out of such oillce or like place to be reproduced. This practice is undesirable for a number of reasons and among which is the fact that there is always the danger that original documents thus sent out of the oice or like place to be reproduced might be lost in transit, and there is the added disadvantage that while the photocopies are being made, the original documents would be out of the oillce or like place and unavailable for reference thereto or other use, when required.

Accordingly, a primary object of our invention is to effect and realize a; photocopy or like machine which may be placed in oiiices and like places, and which may be used to reproduce legal and other documents without the necessity for sending such documents out of an oiilce or like place to be reproduced, and which is so simple in operation that it may readily be operated by persons unskilled in the photographic and like arts.

Another object of our invention is to construct and arrange the new machine in such a manner that the position of the focusing lens which is embodied therein may be readily adjusted or varied by novel means and in a novel manner.

One oi the more diiilicult operations which is involved in obtaining a. desirable photocopy, or like reproduction, is to properly focus the usual photocopy machine, and it has been found that file clerks, stenographers and other employees ordinarily employed in oilices, and like places, and who are unskilled in the photographic and like arts, experience dimculty in properly focusing the usual photocopy machine.

Accordingly, it is another object of our invention to construct and arrange the new photocopy or like machine in such amanner that when it has been initially focused at the factory, or upon delivery to the cnice or other place of business where it is to be used, it will not be necessary, in general, or frequently, to re-focus it during the majority of uses to which it will normally be put thereafter.

Another object of our invention is to construct and arrange fthe new photocopy or like machine in such a manner that the necessary time of exposure involved in taking the picture with the new machine is automatically timed or regulated by the operation of the machine.

A further object; of our invention is to provide an automatic power-driven portable photocopy or like machine which may be used in oflices and like places.

Another object of our invention is to construct the new photocopy or like machine in such a. manner that, after a cycle of operations has been initiated, all phases of the cycle of operations of the machine are performed and timed automatically.

A further object of our invention is to construct our new photocopy or like machine in such a manner that it will automatically stop after a cycle oi operations thereof has been completed.

The usual oice, such as an insurance or law ofiice, does not customarily have the skilled employees necessary to properly develop and print photostats, or like photographic reproductions. Therefore, it is desirable that after the desired exposure or exposures have been made upon light-sensitive paper or like material, to remove the exposed light-sensitive paper from the ma.'- chine and send it rto a photostat or like photocopy company for developing and printing, and

' it is likewise desirable that the exposed paper be immediately replaced with new or unexposed photo-sensitive paper, so that the photocopy or like machine need not be shut down while the iirsrt or previously exposed sheet of photo-sensitive paper or like material is being developed.

It will also be understood that upon removal of the exposed photocopy or like paper from a photocopy or like machine it must be entirely shielded from light in order to protect the exposures made thereon.

Accordingly, another object oi our invention is to effect and realize a photocopy or like machine wherein the light-sensitive paper is contained in a removable housing or magazine, which may be expeditiously removed from the machine in such a manner as to effectively shield the previously exposed light-sensitive paper from light, and which housing or magazine may be quickly and easily replaced in the machine by another and similar housing or magazine containing a new supply of unexposed light-sensitive photocopy or like paper.

Another object of the invention is to construct and arrange the new photocopy or like machine in such a. manner that the web-advancing means, which is associated with the replaceable magazine or housing in which the web or roll of light- Sensitive paper is contained, may be automatically operatively interconnected to or coupled with driving means in the machine by merely inserting the said magazine or housing into its intended and proper or operative position in the machine.

A further object of our invention is to construct and arrange the new photocopy or like machine in such'a manner that the article which is to be reproduced thereby may be quickly and readily placed thereon in position to be reproduced.

Another object of our invention is to effect and realize a photocopy or like machine wherein, upon each operation of the machine, a denite and predetermined length or extent of a web of lightsensitive paper or like material is fed into position to be exposed during the next succeeding operation of the machine.

An additional object of the invention is to construct and arrange the new photocopy or like machine in such a manner that the electrical control circuit for the and the electrical control circuit for the operating motor which is embodied in the new machine are both substantially simultaneously and automatically opened or broken at the end of each cycle of operations of the machine but both of which circuits are under the control of a single manually operable control switch which is said circuits and initiate a the machine.

Still another object of the invention is to construct and arrange the new machine in such a manner as to assure that the advancement of the web of light-sensitive paper or like material, relative to the light aperture in the replaceable magazine, will commence immediately after the shutter has closed, and to assure that the advancing movement of the web of light-sensitive paper or like material, relative to the light aperture in the magazine 2|, will be completed and the machine stOppcd a substantial length of time before the trailing edge of the light shutter uncovers the focusing lens so as to eliminate any possibility that the shutter will leave the focusing lens uncovered at the end of a cycle of operations ofthe new machine and thus destroy a part of the web of light-sensitive paper or like material. v

Other and further objects of the present invention will be apparent from the following description and claims, and are illustrated in the accompanyingdrawings which, by way of illuscycle of operations of illuminating means, e

manipulated to close tration, show a preferred embodiment of the invention and the principles thereof and what We now consider to have contemplated applyingr these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

General statement of the construction andV operation of the machine The new photocopy or like machine, as best shown -in Fig. 1, comprises a casing 2|) which is divided into an illuminated chamber or compartment A and a dark chamber or compartment B by apartition wall 81-89. A window GSi-1|, opening into the illuminated chamber A, is provided in the upper wall 55 of the casing 20, on which the object or document to be reproduced may be placed. Lights 93, 84, 85 and 86 are provided within the illuminated chamber or compartment A and are positioned to illuminate the window 69-'|| and the` object or document positioned thereon during the operation of making a photocopy or like reproduction of said object or document.

A removable or replaceable housing or magazine 2| is replaceably inserted into the dark chama web of light-sensitive paper said web 39 being adapted to be advanced, by means which includes a driving mechanism 54 in the machine, past a light aperture 3| which is formed in a Wall of the magazine 2|.

A focusing lens is mounted in the partition wall 81-89 and is so positioned that during the operation of the new photocopy or like machine it will direct an image of an object or document mounted or disposed on the window Bil-1|, which is illuminated by the lights 81-89, onto that portion of the web f light-sensitive paper 39 which is framed in or in registry with the light aperture 3| in the housing or magazine 2|.

A light shutter ||9 is rotatably mounted in the casing 20, between the focusing lens and the light aperture 3| in the magazine 2|, this shutter 9 being driven by the driving mechanism 54, during the operation of our machine, successively to uncover and then cover the focusing lens and so to control the light passing from the focusing lens into the light aperture 3| of the magazine 2|.

A cycle of operations of the new machine is initiated by depressing or closing a. manually operable control switch |89 which is movably mounted in the top wall 55 of the casing 20, and

out switch |19 driven by the driving mechanism 54, and which switch |19 operates to automatically stop the machine upon completion of a cycle of operations thereof.

After the desired number of exposures has been made upon the web of light-sensitive paper or like material 39 in the magazine 2|, the magazine 2| containing the exposed web of paper or like material 39 is removed from the casing 29, through an opening which is provided in the rear wall 58 thereof, and taken to the place of business of a photocopy or like company, where the exposed web 39 1s removed from the magazine 2| and developed and, in the meantime, the magazine thus removed from the casing 20 is replaced by another magazine 2| containing a fresh or unexposed web of light-sensitive paper or the like material 39, whereupon the foregoing cycle of operations may be repeated.

The construction and operation of the new machine will be more readily understood from a study of the appended. drawings in connection with the detailed description of the new machine which will now be set forth.

Detailed description of the construction of the machine The casing 20 of the new machine includes a top wall 55, a bottom wall 58, a front wall 51, a back wall 58, and side walls 59 and 60. A removable door 6| is provided in the rear wall 58 o f the casing 20 so as to allow easy access'to the inner portion of the casing 20 and so as to facilitate the insertion and removal of the replaceable magazine 2|.

As shown in the drawings (Fig. 5) the removable rear door 6I of the casing 20 is preferably provided with two handles 62 which are attached to its outer face 63, and'when the door 6| is in its normal or closed position a group of relatively long hooks 64, which are attached to the inner face 65 of the door 6| along the upper edge portion thereof, engage a flange 66 4which is formed on the rear wall 58 of the casing '20, and a group of relatively short hooks 61, which are attached to the inner face 65 of the door6| along the lower edge portion thereof, engage a flange 68 which is formed on the rear wall 58 of the casing 20. The hooks 64 and 61 `are so positioned and y proportioned that when the lower hooks 61 are resting upon the flange 68 the upper hooks 64 are still disposed in engagement with the flange 66, but when the door 6| is raised (by means of its handles 62), the maximum distance allowed'by the engagement of hooks 64 and flange 66, the lower hooks 61 are raised above the flanges 68 so that the lower portion of the door 6| may be swung outwardly and thus the door 6| may be completely removed from the casing 20 to facilitate insertion and removal of the magazine 2|.

The front central portion of the top wall 55 of the casing 20 is provided witha cut-out portion or window 69. Filanges are provided around the peripheral edge portion of the cut-out pordow 69-1| and will not allow light from the bulbs 83, 84, 85 and 86 to shine directly downwardly toward the bottom wall 56 of the casing 20.

Disposed in the housing 20, below the window 69-1I, is a vertical partition wall 81 which extends upwardly from the bottom wall 56 of the casing 20. A flange 88 is formed on the bottom edge portion of the vertical partition wall 81. and this flange rests on the upper surface of the bottom wall 56 of the casing 20.

From the upper edge portion of the vertical partition wall 81, an angularly extending partition wall 89 extends or continues upwardly and rearwardly within the casing (Fig. 1).

Flanges 90 and 9| are formed on the side edge portions of the vertical partition wall 81 and when the partition Wall 81 is in position in the casing 20 the anges 90 and 9| slidably but snugly bear against the side walls 59 and 60, respectively, of the casing 20. Flanges 92 and 93 are formed on the side edge portions of the angularly extending partition wall 89 andvwhen this wall 89 is in position within casing 20 the flanges 92 and 93 also slidably but snugly bear against the side walls 59and 60, respectively,lof the casing 20. Thus it will be seen that'the vertical partition partition Wall 81, together with the angularly extending partition wall 89, which is, in effect, a continuation of the partition wall B1, form an effective shield to prevent the passage of light from the illuminated front compartment or chamber A into the rear compartment or magazine chamber B of the casing 20.

Slotted brackets 94 and 95 (Fig. 2) are pivot-` ally connected to the vertical partition wall 81, adjacent the side Walls 58 and 60, respectively, of the casing 20, by means of lugs 98 and 91` and pins 98 and 99, respectively. These brackets 94 tion or window 69 and extend suiliciently inwardly thereof so that a sheet of glass 1|, or like transparent material, may be placed upon the inwardly extending portion of the flanges 10 in such a manner that the upper surface of the glass plate 1| lies in a horizontal plane slightly below the plane of the upper surface of the top wall 55 of the casing 20 (see Fig. 1).

A cover plate 12 is hingedly attached, as at 14', to the top wall 55 of the casing 20, and is provided with a handle 13. The cover plate 12 is so positioned that it will completely cover the cut-out portion or window 69 when in lowered position,

as shown in Figs. 1 and 5.

Arranged in the casing 20, below the window 69-1| (Figs. 1 and 5), are suitable supporting members, vsuch as rods 15, 18 and 11, which are secured to the front wall 51, and side walls 59 and 60, respectively, and a fourth supporting member or rod 18 is secured to the rearwardly extending end portions of the rods 16 and 11. Reflectors, such as 19, 80, 8| and 82, are secured to the rods 15, 16, 11 and 18, respectively, and arranged within the reflectors 19, 80, 8| and 82 are light bulbs 83, 84, 85 and 86.` The reflectors 19, 80, 8| and 82 are arranged in such a manner that they will reflect light from the bulbs 83, 84, 85 and 86, respectively, upwardly toward the winand 95 are, in turn, connected to brackets |00 and |0I, respectively, by means of screw and slot connections |02-|04, and |03-I04a, and the brackets |00 and |0| are rigidly attached, as by welding, to the side walls 59 and 60, respectively, of the casing 20. Screws |02 and |03 engage the slots |04 and |04a in the slotted brackets 94 and 95, respectively, and are screwed into holes which are tapped'into the brackets |00 and |0 I, respectively.

Slotted brackets |05 are `also pivotally connected to the angularly extending partition wall 89,'adja'cent to the flanges 92 and 93, by means of lugs |06 and pins |01 and these slotted brack-V ets |05 are slidably engaged with brackets |08 by means of screw and slot connections |09| I0, the brackets |08 being `rigidly attached to the side walls 59 and V60 of the casing .20 (only one bracket |05 being shown, Fig. ll). Screws |09 engage the slots ||0 in the slotted brackets |05,

andare screwed into holes which are tapped into the brackets |08.

It is known that therefractory properties of focusing lenses vary considerably and hence it is necessary, in a'machine such as the new photocopy machine, to provide means for adjusting the position of the focusing lens lrelative to that portion of lthe web of photo-sensitive sheet material 39 onto'which the image of the object various focusing lenses which may bc used in ylens includes a lens tube the machine or because of damage tothe focusing lensinitially provided with the machine.

Another reason for mounting the focusing lens u in the adjustable partition wall 81-89 in the new machine is to provide a simple but eiective means for regulating and varying the size of the image cast upon the web of photo-sensitive paper 39, Which may be accomplished by adjusting the focal point of the focusing lens relative to the web of photo-sensitive paper 39, as will be readily understood by persons` skilled in the art.

. When the vertical partition wall "81 and the angularly extending partition wall 89 are in operative position in the casing 20, the screws |02, |03 and |05 hold the slotted brackets 93, 35 and 38 tightly against the brackets |00, |0| and |08, respectively, and thereby securely hold the partition walls 81 and 89 in position. However, if and when it is necessary or desired to move or adjust the partition walls 81 and89 to another or different position in the casing 20, this may be accomplished by loosening the screws |02, |03 and |05, sliding the partition walls 81 and 89 backwardly or forwardly as desired, and then securely'tightening the screws |02, |03 and |05 so as to hold the partition walls 81 and 89 in the desired position in the casing 20 into which they have been adjusted.

A focusing lens is mounted in the vertical g partition Wall 81. This focusing lens is composed of a rear section ||2' and a front section H3, as best seen in Figs. 1 and 2. The rear section ||2 of the focusing lens includes a rear lens housing l IQ, in which is mounted a lens (not shown), and the front section |3 of the focusing |6 within which is mounted a-lens (not shown), and a prism IIS is mounted on the front or outer end portion of the lens tube I8, as is best seen in Figs. 1 and 2.

The removable magazine or housing y2| includes side walls 24 and 25, a top wall 26, a rear wall 21, a bottom wall 28, and a front Wall '29 which is movably attached to the side wall 23 as by hinges 30. The front wall 29 has a light aperture 3| formed therein; said light aperture 3| having dimensions slightly larger than the largest photostat or other photocopy which the new machineis capable of making.

Arranged in the replaceable housing or magazine 2|, rearwardly of the light aperture 3|, is

4a vertically extending guide member 32 which has suitably rounded upper and lower edge portions, 33 and 34, respectively, and this guide member 32 is attached by hinges 35 to the side Wall 2d of the magazine 2|. normal or operative position, extends perpendicularly relative to the side wall but positively held in this position by means gf, a suitable latch 38, which is shown in Fig. 2, and when in its normal position, as in Fig. 1, the front face 31 ofthe guide 32 completely covers the light aperture 3| but is spaced slightly to the rear thereof, as shown in Fig. 1. o

A supply or web of light-sensitive photocopy or like paper 39 is rolled orl wrapped upon a feed roll 22 which is disposed in the replaceable magazine 2| and, when the new photocopy or like machine is properly assembled for operation, the web of light-sensitive paper or like material' 39 extends from the feed roll 22, across the front face 31 of the guide 32, in close contact the-re. with and in such a manner that it is horizontally centered directly behind the light aperture 3| in 24 and is releasably,

or sensitized face Q0 light aperture 3 From the guide 32 the web of light-sensitive paper or like material 39 extends rearwardly to a take-up roll 23, which is rotatably mounted in the magazine 2|, and onto which it is wound during operation of the machine, and the rounded edge portions 33 and 34 of the guide 32 prevent creases or sharp bends from being formed in the web 3S as it is drawn tightly across the front face 31 of the guide 32.

The take-up roll 23 is mounted upon and secured t0 a shaft 3|, and the end portions of the vof the web-39 facing the shaft 6| are slidably and rotatably mounted in vertically extending slots 42 which are formed in brackets `43, one of the brackets i3 being mounted on each of the side walls 2d and 25 of the magazine 2| It will be noted that take-up roll 23 may easily be placed in position in the magazine 2| by lowering the end portions of the shaft All, into the slots 32, through theopen upper ends M thereof, until the take-up roll 23 rests upon the drive roller 45.

A weighted roller 223 is mounted in the magazine 2|, upon ashaft 224 which is carried by a lever 225 which is pivotally mounted, as at 221, upon a bracket 228 which is secured to the rear `wall 21 of the magazine 20. This weighted roller 223 may be swung up, out of the way, when inserting the take-up roll 23 into the magazine 2| but, when the take-up roll 23 is in position in the magazine 2 the weighted roller 223 is allowed to rest upon the take-up roll 23, thus keeping the latter in tight contact with the drive roller 45.

The drive roller 45 is secured on shaft 36 which has one end portion 4l thereof journaled in a bearing i8 which is mounted in the sidewall 25 of the magazine 2|. The other end portion 38 of shaft 56 is journaled in and extends through a bearing 50 which is mounted in the side Wall 23 of the housing 2|.

One element 5| of a clutchor coupling 52 is secured to the outer extremity of the end portion .43 of the shaft d6. The clutch or coupling element 5| is adapted to engage a complementary The guide, 32, when in itsv the replaceable magazine 2| and with the front 75 clutch or coupling element 53 which forms a part of a driving mechanism-56, which is arranged in the casing 20, and this coupling or clutch 5|53 establishes a severable connection between the driving mechanism 54 and the shaft '46 and drive roller 45 so as to revolve or rotate the take-up roll 23, thereby advancing the-.web of light-sensitive paper or like material 39 from the feed roll 22 onto the take-up roll 23, as will be more fully described hereinafter.

In a photocopy or like machine, such as the present machine, it is necessary to provide some means which will allow the light-sensitive paper or like material in the machine to be exposed yfor the proper length of time to a well lighted far, and by reference to Fig. 1 of the drawings,

it will be seen that when the magazine 2| is positioned in `the casing 20, and the rear door 63 of the casing 20 has been closed, the only source from which light may pass from the light chamber A into the rear or dark chamber B, and thence galassia into the magazine 2|, so as to imping,` upon the web of light-sensitive paper 39 within the magazine 2|, is by way of the focusing lens |I|.

The new photocopy or like machine includes a light shutter ||9 which is rotatably mounted in the casing 20, directly behind the focusing lens on a shaft |y which is driven by the driving mechanism 54, as will be explained presently.

In view of the fact that varying conditions in lighting and the like may be encountered in the use of the new machine, it may be necessary to change the time of exposure during which a picture is taken upon the web of paper or other light-sensitive material 39, and hence the shutter ||9 is preferably made adjustable. Referring to Figs. '1 and 8, it will be noted that the shutter ||9 includes two separate shutter blades |23 and |24, both of which are mounted on the shaft |20, and that the shutter blade |23 includes a portion |2| which provides the trailing edge of the shutter while the shutter blade includes a portion |22 which provides the leading edge of the shutter ||9.

The shutter blades |23 and |24 are of like size and configuration and are adjustably fastened together by means of a screw |25 which is inserted through a slot |26 which is formed in the shutter blade |24, this screw |25 being screwed into a hole which is tapped into shutter blade |23. The shutter blade |24 is fast to the shaft |20 but the shutterblade |23 is revolvable upon, and relative to the shaft |20, and is dependent upon the screw and slot connection |25|26 made with the shutter blade |24 for its positive connection to the shaft |20.

It will be noted that when the parts are disposed in the position in which they are shown in Fig. '1, the shutter blades |23 and |24 are arranged in exact coincidence with each other and thus are set for the longest possible exposure time, or conversely, are set for the shortest possible time that the shutter ||8 will be positioned directly behind the focusing lens l| during a cycle of operations of the machine.

The shutter ||9 is shown in Fig. 8 with the blades |23 and |24 thereof in a p'artially spread 'or farmed position and, it will be noted, that in this position of the parts the shutter blade |23 has been adjusted or rotated rearwardly rela.

tive to the shutter blade |24 but is held by the screw and slot connection |25-|26. When the shutter blades |23 and |24 are disposed in the position in which they are shown in Fig. 8, the exposure time, that is, the time during which a reproduction is taken, is comparatively short, relative to the exposure time required when the shutter blades |23 and |24 are disposed in the position in which they are shown in Fig. 7.

It will also be noted that when the parts are disposed in the position in which they are shown in Fig. 8, the leading edge |22 of the shutter ||9 is disposed in the same position as that in which it is shown in Fig. '7, and will operate to cut oi the light from the focusing lens and end the exposure of the web of light-sensitive paper 39 in the magazine at the same point or interval in a cycle of operations of the machine as before, although the shutter I|9 will have to be rotated a substantially greater circumferential distance than previously before the exposure of the web of light-sensitive paper 39 will be initiated by the uncovering of .the focusing lens by the trailing edge |2| of the shutter blade |23.

By making the shutter ||9 adjustable in the manner described above, it is possible for the advancement of the web of light-sensitive material 39, past the light aperture 3| in the magazine 2|, to be commenced immediately after the shutter I I9 has become closed and to assure that the advancing movement of the web 39, relative to the light aperture 3|, will always have been completed and the machine stopped a substantial length of time before the trailing edge |2| of the shutter blade |23 again uncovers the focusing lens Hence, any danger that a person operating the new machine will improperly adjust the shutter IIS so as to leave the focusing lens uncovered at the end of a cycle of operations of the machine, is eliminated.

Referring now to Figs. 2, 3 and 6, wherein the driving or motor-driven operating mechanism of the machine is best illustrated, it will be noted that this driving mechanism, which is generally indicated at 54, includes an electric motor |21 which is mounted on a supporting base |28 which is disposed in the casing 20. The armature shaft |29 of the motor |21 is attached to a shaft |30 by means of a suitable coupling |3|. The shaft |30 extends into a gear housing |32 and, through suitable reduction gear (not shown) but which are enclosed in the gear housing |32, the shaft |30 drives a shaft |33. A helical gear |34 is secured to the shaft |33, intermediate the ends thereof (Fig. 6), and meshes with a helical gear which is secured to a shaft |36.

The shaft |36 is journaled in bearings |31 and |38 which are formed in vertically extending arms |39 and |40, respectively, of a supporting member |4I, which is secured to the upper surface of the supporting base |28. Collars |44, and |46` which are suitably secured to the shaft |36 by means of pins, screws or the like, maintain the shaft |36 in a fixed longitudinal position within the bearings |31 and |38. A sector gear |41, having a hub |48, is positioned on the inner end portion of the shaft |36 and is suitably secured thereto. Gear teeth |50 are provided on a portion of the peripheral edge of the sector gear |41 and the remaining portion |5| of the peripheral edge of the sector gear |41 lies on or slightly within the dedendum circle of the gear teeth |50.

Extending parallel to and disposed directly above the shaft |36 is a shaft |52 which is journaled in bearings |53 and |54 which are formed in the vertically extending arms |39 and |40, respectively, of the supporting member |4. Collars |55 and |56 are secured to the shaft |52 on opposite sides of the bearing |53 and these collars |55 and |56 maintain the shaft |52 in fixed longitudinal position within the bearings |53 and |54. A gear |51, having teeth |58, is secured to the shaft |52 in such position that the teeth |58 will engage the teeth |50 of the sector gear |41 and be rotated thereby during that portion of the rotation of the sector gear |41 in which the teeth |50 thereof extend upwardly from the sector gear |41 and are positioned directly below the shaft |52 and its gear |51.

It will be noted, in this connection, that the gear |51 and the shaft |52 are so positioned that during the remaining portion of the rotation of the sector gear |41, that is, when the gear teeth |50 are not positioned directly below the gear |51, the gear teeth |58 of the gear |52 will be vertically spaced above the sector gear |41 so as not to engage the peripheral edge portion |5| of the sector gear |41, which lies within the dedendum circle of the gear teeth |50, and that, therefore, the sector gear |41 will turn through this portion of its rotation without the gear |51.

A clutch or coupling element 53 is secured to the inner end portion of the shaft |52, inwardly of the gear |51. Lugs |60 are' provided on the inner face |59 of the clutch or coupling element 53. The lugs |60 are complementary to grooves |6| which are provided in the outer face |62 of a clutch or coupling element which is secured to the shaft 46, as previously described.

When the replaceable magazine or housing 2| is disposed in its intended or operative position Within the casing 26, the lugs |60 on the clutch or coupling element 53 engage the complemenlmparting movement to tary grooves |6| which are formed in the clutch or coupling c ement 5|, thus operatively connecting or engaging the shaft 46 of the magazine 2| to or with the shaft |52 of the driving mechanism 54.

It will be noted, in this connection, that the weight of the magazine 2| is such that the friction between the plate |63, which connects the supporting legs |64 of the vhousing 2|, and the bottom wall 56 of the casing 20, is sullicient to maintain the housing 2| in position within the casing and thereby maintain the clutch or coupling element 5| of the magazine 2| in engagement with the clutch or coupling element 53 of the driving mechanism 54.

A sprocket wheel |65 is mounted on the shaft |33 of the helical gear |34 and this sprocket wheel |65 has teeth |66. A sprocket chain |61 engages the teeth |66 of the sprocket wheel |65 and drivingly connects the sprocket wheel |65 to a corresponding sprocket wheel |68 which is secured to a shaft |69 which is journaled in bearings |10 and |1| which are mounted on the su porting base |28 of the machine.

A sprocket wheel |13 is secured to the shaft |69 forwardly of the sprocket wheel |68. A chain |14 connectsthe sprocket wheel |13 and theshaft |69 to a sprocket wheel |15 which is secured on the rear end portion of the shaft |28 on which the shutter |I9 is mounted, said shaft |20 being journaled in a hearing |16 which is formed in the vertically extending arm |11 of a supporting member |18 which is secured *o the upper surface of the supporting base |28 ofthe machine.

A stop-switch rotor |19 is secured to the shaft |69 intermediate the sprocket wheels |13 and |68, and this rotor |19 includes a.v conductive surface |80 and a non-conductive surface I8I. Contact rollers |82 and |83 are secured to the upper surface of the supporting base |28 so that they may engage and roll upon the conductive surface |88, and non-conductive surface |8|, of the stop-switch rotor |19.

The Contact rollers |92 and |83 are attached to conductors |84 and |85, respectively, which form part of the operating circuit (Fig. 9) for the electric motor |21. When the motor |21 is running, the contact rollers |82 and |83 are maintained in rolling contact with the conductive surface |89 of the stop-switch rotor |19 and the electrical connection between the conductors |82 and |83 is thereby completed. However, at the end of a cycle of operations of the machine the insulating or non-conductive strip .|8I contacts the rollers |82 and |83 and the electrical connection between the conductors |84 and |85 is thereby broken, thus deenergizing a relay |86 and allowing the switch blades |81 and |88 to open, which causes the motor |21 to stop and the elec-V trical circuit to remain open until another oper- The gear ratio between the shaft |33 and all of the other shafts |36, |52, |69, 46 and |20,

The circuit through the stop-switch rotor room so as to avoid exposure o Switch rotor |19, contact roller which are directly or indirectly driven thereby, is one to one. Therefore, upon a single rotation of the shaft |33 the shafts |69, |20, |36 and |52 are each caused to make a single revolution and thereby cause the shutter I9, which is secured to the shaft 20, as well as the drive roller 45 on the shaft 46 (which is connected to the shaft |52 by means of the clutch 52) to make one com plete revolution, as will be described more fully hereinafter in connection with the description of the operation of the new machine.

'Ihe new machine includes, in general, four electrical circuits which are diagrammatically illustrated in Fig. 9, namely, a starting circuit which is associated with the manually operable starting switch |89, an operating circuit for the motor |21, a control circuit for the illuminating lamps 83, 84, 85 and 86, and a circuit through the stop-switch rotor |19.

'I'he starting circuit which is associated with the manually operable starting switch |89 includes a line conductor |92, conductor |93, Switch contact 9|, starting switch |89, switch contact |90, conductor |94, conductor |95, coil |96 of the relay |86, conductor |91, conductor |96, conductor |99, and the line conductor 206.

The operating circuit for the motor |21 includes the line conductor |92, a conductor 204, switch blade |88, switch contact point 203, condoctor 206, motor |21, conductor 201, conductor |96, conductor |99, and the line conductor 200.

The control circuit for the illuminating lamps 83, 84, 85 and 86, includes the line conductor |92, a conductor 204, conductor 205, switch blade |81, switch contact point 202, conductor 208, conductor 209, illuminating lamps 83, 84, 65 and 96, conductor 2 l0 and the line conductor 200. |19 conductor 204, switch contact includes the line conductor |92, conductor 205, switch blade |81,

point 202, conductor 268, conductor |85, contact roller |83, conductive surface of the stop |82, conductor |84, conductor |95, relay coil |96 of the relay |86, conductor |91, conductor |98, 'conductor |99 and the line conductor 200.

Operation with a roll of photo-sensitive paper or like material 39, as will now be described; it being preferable that the magazine 2| of the photosensitive paper 39.

the magazine 2|, is then released and the guide 32 swung outwardly, that is, into open position, about its hinges 35. f-

When the front wall 29 of the magazine 2| and the guide 32 are disposed in open position, the feed roll 22, with a roll of photo-sensitive paper 39 arranged thereon, may then be inserted into the magazine 2| and the end portions of the rod 22A, which extends through the center be loaded in a dark operating or of the feed roll 22,` may be positioned in the grooves 22B which are formed in the Aupper edge portion of the feed roll supporting brackets 22C which are attached to the walls 24 and 25 of the magazine 2|, in the manner which is illustrated in Fig. 1.

The weighted roller 223 may then be swung into a vertical position, upon its pivot 221, which is secured to the bracket 226 The free end portion of the roll of photo-sensitive paper v39 may then be secured to the take-uplroll 23 in any suitable manner, such as, for example, by inserting the edge portion of the free end portion oi the photo-sensitive paper into a slot formed in the take-up roll 23. The take-up roll 23 may then be inserted into the magazine 2| and positioned so as to rest upon the drive roller 45, this being accomplished 4by lowering the end portions of the shaft '4| of the take-up roll 23 into the slots 42 which are formed in the brackets 43 which are secured to the walls 24 and 25 of the magazine 2|.

The guide 32 may then be placed in closed position in the magazine 2| 'so as to bear against a loop of photo-sensitive paper 39 which may.

be drawn from the feed roll 22 whereupon the slack in the web of photo-sensitive paper 39 may then be rewound onto the feed roll 22, thereby drawing the web of photo-sensitive paper 3 tightly across the guide 32. The front wall 29 of the casing 2| may then be swung into closed position whereupon the magazine 2| is ready to `be inserted into the casing 28 of the new machine. l

The insertion of the magazine 2| into the cas-X;

ing 20 is accomplished by removing the rear door v68 of the casing 20, as previously described, and then inserting the magazine 2| into the casing 20 through the door opening which is formed in the rear wall 58 of the casing 28. Whenthe magazine 2| is inserted into the casing 20 it rests upon the bottom wall 56 of the casing 28 and may be slid into operative position in the casingv 28 and in which position the groove |6| Which-is formed in the clutch or coupling element which is positively connected to the drive roll 45, operatively engages the complementary lug |68 which is formed :m the clutch or coupling element 53 which forms a part of the driving mechanism 54.

From the vforegoing descr1ption, it will, there: I

fore, be seen that thev placing or manual insertion of the magazine 2| into operative position in the casing 28, automatically couples or connects the web-advancing mechanism -23 -22 in the magazine 2| to the motor-driven driving mechanism in the casing 28, and that this arrangement ,facilitates thc insertion of the replaceable magazine 2| into the casing 28 as well as its removal therefrom.

A cycle of operations of the machine is initiated by the closing of the manually operable control switch |89, which is movably mounted on the top wall of the casing 28, a new or used portion of .the web of light-sensitive paper 39 being positioned behindy the Vlight aperture 3| in the magazine 27|. I.- The pressing of the manually operable control switch` |89 completes electrical circuits, which are shown in Fig. 9,

in a mannerwhich will be described presently, c

so as to illuminate the light bulbs 83, 84, and 86 and set the motor |21 in operation,

Referring now to Fig. 9, it will be noted that the wiring diagram therein set forth illustrates the electrical circuits embodied in our machine ductor 208, through the `rial that the contact rollers |82 and |83 in the open or non-operating position which they assume prior to the initiation of a cycle of operations of the machine. As illustrated in Fig. 9, the manually operable starting switch |89 is open, and the relay |86 isdeenergized so that switch blades |81 and |88 are also open, andthe stopswitch rotor |19 has overrun slightly so that the contact rollers |82 and |83 are in contact with the conductive surface |88 of the stopswitch rotor |19.

It will be noted, however, that it is immateare disposed in contact with the conductive surface |88 of the stop switch rotor |19, tion of a cycle of operations of the machine, because both the starting switch |89 and the switch blades |81 and |88 are open so that no current may flow through the circuit, and, therefore, the operating motor |21 is stopped.

When it is desired to set the new machine in operation, the manually operable starting switch or push button |89 is momentarily depressed, thus closing contacts |98 and 9|. The closing of the starting switch |89 closes an electrical circuit (Fig. 9) and current then flows from the line conductor |92, through the conductor |93, through y the contact |9|, through the starting switch |89, through the contact |98, through the conductor |94, through the conductor |95, through the coil |96 of the relay |86, through the conductor |91, through the conductor |98, through the conductor |99 and back into'tlie other line .conductor 208. The momentary closing of the starting switch |89 thus causes the relay |86 to be energized and the core 20| of the relay |86 is magnetized causing the switch blades |81 and |88 to be drawn against contact points 202 and 203, respectively.

The energization of the relay |86, in the manner described above, is instantaneous so there is no appreciable lag in the closing of switch blades |81 and |88, and' upon the closing of the switch blades |81 and |88, circuits through the motor |21 and the lights 83, 84, 85 and 86 are instantaneously completed.

vthrough the conductor 286, through the motor |21, through the conductor 201, through the conductor |98, through the conductor |99 and into the other line conductor 200.

The light or illuminating circuit (Fig. 9) is completed by the closing of the switch blade |81, whereupon the current ows from the line conductor |92, through the conductor 284, through the conductor 285, through the switch blade |81, through the contact point 282, through the conconductor 289, through the lights83, 84, 85 and 86, through the conductor 2 |0 and into the other line conductor 288. The lights 83, 84, 85 'and 86 may be arranged in parallel or in series, as desired, depending on whether it is desired to have high or low voltage lights, as will readily be understood by those skilled in the art. Invthe preferred embodiment of our invention which is shown in the drawings, however, we have shown high voltage lamps arranged in parallel, but if so desired, a series arrangement of low voltage lights may be easily substituted therefor by anyone skilled in the art.

If the shaft |69 and the stop-switch rotor |19 have stopped, at the end of a previous cycle of prior to the initiaoperations of the machine, in such a position that the contact rollers |82 and |83 remain in contact with the narrow insulating or non-conductive strip I8I, the electrical circuit through the stopswitch rotor |19 is not instantaneously completed upon the closing of the switch blades |81 and |88, but is completed only after the operating motor |21, through the driving mechanism 54, has rotated the shaft |69 and the stop-switch rotor- |19 suciently to enable the contact rollers |82 and |83 to engage the conductive surface I 80 ofthe stop-switch rotor |19. However, the operating motor |21 rotates the shaft |69l so quickly that the completion of the circuit is practically instantaneous, since it is practically impossible to give the manually operable starting switch |89 such a rapid depression or manipulation that the shaft |69 fails to move sufficiently to close the circuit. However, the overrun of the shaft |89, though necessarily very small, is usually sulicient to move the narrow insulating or' non-conductive strip I8| out of contact with the contact rollers |82 and |83 so that the contact rollers |82 and |83 are already in engagement with the conductive surface |80 of the stop-- switch rotor |19 when the manually operable starting switch or button |89 is depressed to initiate an operation of the machine.

Hence, it will be seen that either at the instant the starting switch or button |89 is depressed or a fraction of a second later, after the switch blades |81 and |88 are closed, circuit through the stop-switch rotor |19 is completed. This circuit is the essential circuit during the normal operation of the new machine, after the starting switch |89 has been released and is open, because it is this circuit which maintains the relay |86 in an energized condition and. therefore maintains the switch blades |81 and |88 in a closed position.

In -the circuit through the stop-switch rotor |19, current iiows as follows: from the line conductor |92, through the conductor 284, through the conductor 285, through the switch blade I 81, through the contact point 202, through the conductor 288, through the conductor |85, through the ccitact roller; |83, through the conductive surface |88 of the stop-switch rotor |19, through the contact roller |82, through the conductor |84, through the conductor |95, through the relay coil |96 of the relay |88, through the conductor |91, through the conductor |98, through the conductor |90, and into the line conductor 288. Therefore, it will be understood that -after the motor'l21 has started, and while the contact rollers |82 and |83 are maintained in contact with the conductive surface |88 on the stop switch rotor |19, circuit is maintained through the coil |98 of the relay |88, even though thestarting switch |89 has been allowed to open. Hence, the relay |88 is maintained in an energized condition and the switch blades |81 and |88 are thus maintained in engagement with contact points 202 and 203, respectively, and therefore the parallel circuits through the lights 83, 84, 85 and 86 and through the operating motor |21 are maintained during'a, ,complete cycle of operations of the machine.

Atthe end of a cycle of operations of the ma- |69 will have made a complete revolution and the narrow insulating or nonconductive strip 8| will break the contact between the contact rollers |82 and |83 and the conductive surface |80 of the stop-'switch rotor |19, thereby cutting off the :IlowA of current n photostatic or like it drives the shaft web of light-sensitive paper through the relay coil |86 of the relay |86, which instantaneously d-eenergizes' 'the relay |86 and immediately allows the switch blades |81 and |88 to open, thereby opening the circuitthrough the operating motor |21, as well as the circuit through the lights 83, 84, 85 and 86, and thus stopping the machine.

When the motor |21 has been set in operation,

|33 through the reduction gearing contained in the gear housing |32. 'I'he shaft |33 drives the shafts |36 and |69 through the gears |38 and I 35 and the ratchet wheels |65 and |68, respectively. During the rstfportion of a cycle of operations of the machine, however, the gear teeth |58 of the gear |41 on the shaft |36, are not disposed in engagement With the teeth |58 of the gear |51 so that the gear |51 and, consequently, the drive roller remain stationary. The rotation of the shaft |69, however, imparts rotation to the sprocket wheel |13 which is fast thereto and thereby, through the chain |18 and the sprocket wheel |15, drives the shaft |28 in a counterclockwise direction as seen in Fig. 6.

The shutter I I9 is fast to the shaft |20 so that during a cycle of operations of the machine, when the shaft |28 is caused to rotate in a counterclockwise direction, as viewed in Figs. 6, '1 and 8, the shutter ||9 will be disposed directlygbehind the focusing lens during part of its rotation but will move away from'and uncover the focusing lens III during the balance of its rotation; the position which the shutter |I9 assumes at the end of each cycle of operations of the machine being illustrated in Fig. 6.

When the shutter I|9 has been adjusted, as shown in Fig. 6, it will be -noted that upon commencing a cycle of operations of the machine, the

end portion |2| of the shutter ||9 will quickly move out from behind the lens II and will then allow an image of the article to be directed from the Window 1|, through the prism II 8 and the focusing lens I I I and thence through the light aperture or opening 3| into the or like material 39. During the next part of a cycle of operations the photocopy will be taken, that is, the light-sensitive paper or like material 39 will be exposed to the image of the article or document being reproduced, and this portion of the operation will conti-nue until the rotation of shaft |28 and shutter |I9 causes the leading tip or edge |22 of the shutter I9 to move behind the focusing lens III, thus cutting oi the light from the focusing lens III onto the web of light-sensitive paper 39.

During the remaining portion of a cycle of operations of the machine, that is, from the time that the leading tip or edge |22 `o f the shutter I9 movesY behind the lens II I until the shutter ||9 has come to a stop in its initial position, as shown in Fig. 6, the light from interrupted by the shutter II9 so that no light reaches the 'web of light-sensitive paper 39, and the necessary parts of the driving mechanism 54 are caused to engage and thus advance the web of light-sensitive paper 39 used portion ofthe web 39 is positioned rearwardly of the light aperture 3| in the magazine 2|, to beexposed during the next succeeding cycle of operations of the machine.

Therefore, it will be noted that anew or unused portion of the web of light-sensitive paper or like material 39 is always positioned behind the light aperture 3| in themagazine 2| upon completion being reproduced -the focusing lens III is so that a new or unshaft |59 engages of a cycle of operations of the machine, and that those portions of the web 39 which have previously been exposed are drawn into the body or interior of the magazine 2| so that if light is subsequently allowed either intentionally or accidentally to strike that portionof the web 39 which is positioned behind the light aperture 3| of the magazine 2| only a new or unused portion of the web 39 will be affected and a double ex-` posure and loss of material will thus be avoided.

During the time the shutter ||9 is turning through the exposure portion of its cycle of rotation, the sector gear |41, driven by the shaft |36, also turns and brings the rst gear tooth |50 into engagement with a tooth |58 of the gear |51, which is secured to the shaft |52. Further rotation of the sector' gear |41 rotates the gear |51 which causes the shaft |52 to rotate and, through the clutch or coupling 52, rotates the shaft 48 and the drive roller 45. The number of teeth |50 on the sector gear |41 is the same as the number of teeth |58 on the gear |51, with which they engage, so that while the toothed portion of the sector gear |41 is moving in engagement with the teeth |58 on the gear |51, through a partial revolution of the sector gear |41, the gear v|51 and consequently the drive roller 45 is turned through a. complete revolution The take-up roll 23, being in close contact with the drive roller 45, a complete revolution of the drive roller 45 causes the take-up roll 23 to rotate and advance the web 39 a distance equal to the circumference of the drive roller 45. The take-up roller 23 being so driven, it is obvious that the web 39 is advanced a predetermined distance, upon each operation of the machine, and this distance does not vary with the size of the take-up roll 23 as would be the case if lthe take-up roll 23 were positively driven, as for instance by gear engagement with the shaft 48.

When the shaft |36 and the sector gear |41 have rotated far enough so that the last tooth |50 on the sector gear |41 has passed into and out of engagement with the teeth |58 on the gear |51, the shutter ||9 has been rotated to a position wherein the trailing edge portion |2| of the shutter ||9 is covering the lens substantially as shown in Fig. 6, and the shaft |69 has made substantially a complete revolution so that the narrow insulating or non-conductive strip |8| of the stop-switch rotor |19 on the the contact rollers |82 and |83 and raises them out of contact with the conductive surface |88 of the stop-switch rotor |19, thus momentarily breaking the electrical circuit through the stop-switch rotor |19 and the relay coil |96, and thereby deenergizing the relay |86 and allowing the switch blades |81 and |88 to open and break the circuits (Fig. 9) through the motor |21 and the lights 83, 84, 85 and 88.

As previously pointed out, however, it is not essential that the stop-switch rotor |19 stop while the insulating or non-conductive strip |8I'engages the contact rollers |82`and |83 for the reason that, even if the stop-switchV rotor everruns slightly so that the contact rollers |82 and |83 again engage the conductive surface |88 of the stop-switch rotor |19, the engagement; with the insulating strip |8| has momentarily broken the electrical circuit through the relay |86, and the switch blades |81 and |88 have thereby been opened so that no closed electrical circuit through the machine is possible until the manually operable control switch |89 has again been depressed or closed.

When the machine has stopped it is ready for a new cycle of operations so that, if another copy of a document previously reproduced is desired, it is merely necessary for the operator to press the manually operable control switch |89 again, whereupon the machine will make a new or second exposure of the article or document which is disposed upon the window 1|. This procedure may be repeated any number of times, depending upon the number o copies of a document which may be desired, and this procedure is especially desirable either in cases Where a number of negatives of the same document are desired or Where exposures of a negative are being made and a number of positive copies are desired.

The removability and the replaceability of the magazine 2| is a matter of practical importance. Thus, for example, if our or ve copies of a document are desired and yet it is known that the machine will be needed for other work before the desired prints could be developed, it is merely necessary, after the desired number of exposures have been made upon the web 39, to remove the rear door 63 from the casing 20, slide the magazine 2| to the left (as viewed in Fig. 6) so that the clutch or coupling element 5| on the shaft 4 6 is disengaged from the clutch or coupling element 53 on the shaft |52, and then remove the entire casing 2|, with the exposed web oi light-sensitive paper 33 therein, through the opening which is formed in the rear wall 58 of the casing 20 and which is normally closed by the door 63 (Fig. l)

The removal of the magazine 2| from the casing 20 exposes that portion of the web 39 -which is disposed immediately behind the light aperture 3| in the magazine 2|, but this is immaterial for the reason that this portion of the web 39 has not previously been exposed to the image of a document, and those portions of the web 39 which have previously been exposed to the images of documents are safely rolled upon the feed roll 23 or are shielded behind the guide 32 so that no light can reach them.

If desired, a cover plate may be positioned over the light aperture 3| in the magazine 20 before removing the magazine 2| from the casing 20, so as to protect that portion of the unused web of light-sensitive paper 39V which lies directly behind the light aperture 3|. However, due to the relatively inexpensive nature of light-sensitive paper or like material, such asis used in the present machine, it is unnecessary to provide a cover plate for the light aperture 3 After it has been removed from the casing 2 0, the entire magazine 2|, containing the exposed web of light-sensitive material 39, may be sent to the developers to have the exposed portions of the paper developed, and while this is being done a second magazine 2|, containing a new or unexposed web of light-sensitive material 39, may be inserted into the casing 29 and additional exposures made without delaying the development of the previously exposed web 39.

Upon inserting a magazine 2| into the casingr 20 it is advisable to run the machine through an idle cycle of operations, i. e., one from which no reproduction is expected, in order to move that portion of the web of light-sensitive material 39, which was positioned behind the light aperture 3|, during insertion of the magazine 2| into the ca'sing 20, out of register with the light aperture 3|, and so as to move a new or unexposed portion,

of the web 39 into register ture 3i in the magazine 2l.

From the foregoing description of our invention it will be apparent that we have provided a. new and improved photocopy machine which is relatively simple in operation and construction and which, by reason of its simplicity and novel features, provides a practical photocopy machine which is particularly adapted for use in oflces and like places.

Many other advantages and novel features of the present invention will be apparent to persons skilled in the art, and while we have illustrated and described a selected embodiment of our invention, it is to be understood that this is capable of variation and modification and we therefore do not wish to be limited to the precise dewith the light apertails set forth -but desire to avail ourselves of such changes and alterations as fall within the purview of the following claims.
